UNIPOLAR ELECTROCARDIOGRAPHY IN PULMONARY STENOSIS

Unipolar electrocardiography in pulmonary stenosis.

Congenital pulmonary stenosis with intact ventricular septum is a relatively common malformation of the heart. The stenosis varies from almost complete obliteration to a minimal decrease in the diameter of the orifice. The stenosis is usually of the valve, but it may be either of the infundibulum or of the lower bulbar orifice. The atrial septum may be complete, imperfectly developed, or it may...

The Importance of Electrocardiography in Pediatric Patients with Pulmonary Arterial Hypertension in Follow- up

Background: Right Ventricular (RV) hypertrophy is an adaptive response to chronic RV pressure overload in patients with pulmonary hypertension. We investigated the relationships between RV hypertrophy indicators, including electrocardiography, the percentage oxygen saturation (SaO2%), body mass index (BMI), and blood uric acid levels in patients with...

Pulmonary valvotomv PULMONARY VALVULAR STENOSIS

Twenty children with pulmonary valvular stenosis were studied by cardiac catheterization both at rest and during submaximal supine exercise, prior to and following pulmonary valvotomy. The resting and exercise states were comparable preoperatively and postoperatively since cardiac output, heart rate, A V 02 difference and oxygen consumption were similar. Evidence of improved cardiac function wa...

Electrocardiography Patterns and the Role of the Electrocardiography Score for Risk Stratification in Acute Pulmonary Embolism

BACKGROUND AND OBJECTIVES Data on the usefulness of a combination of different electrocardiography (ECG) abnormalities in risk stratification of patients with acute pulmonary embolism (PE) are limited. We thus investigated 12-lead ECG patterns in acute PE to evaluate the role of the ECG score in risk stratification of patients with acute PE. SUBJECTS AND METHODS One hundred twenty-five consec...
